Plugging a 2nd controller replaces the one already in port #0, previously plugged controller moves to port #1.

Description

Let say I only have my DualShock 4 plugged, I'll have this:

• Port 0: DS4
• Port 1: disabled

Perfectly normal, now if I plug my 8bitdo N30 Pro, the new one "replaces" my DS4 and the DS4 moves to port 1:

• Port 0: N30Pro
• Port 1: DS4

PLEASE NOTE:

• Idk if it's important or not but this is when using USB ports, I don't have a bluetooth receiver to test wireless.
• It seems to be only happening when xinput and dinput is selected as joypad driver, no issue with sdl2 driver.
• No issue on my Linux VM (udev driver) and on my Android phone (android driver).

I read about this issue yesterday on Discord and wanted to try, I didn't see any issue about it poping up so here we go.

Expected behavior

1st controller stays as player 1 when a new one is plugged.

Actual behavior

2nd plugged controller becomes player 1 and previously plugged controller switches to player 2.

Steps to reproduce the bug

1. Start RA with a single controller plugged and make sure joypad driver is set to x/dinput.
2. Plug a 2nd controller.
3. Check in Settings > Input the position of the controllers.

Bisect Results

Doesnt seem to be a new thing, I went back up to 1.6.7 (the oldest I could get from the buildbot) and it's already acting like that.

Version/Commit

• RetroArch: 1.6.7 stable -> latest 1.7.7 nightly (becfff5 when typing this)

Environment information

• OS: Windows 10
• It doesn't happen on my Linux VM neither with my Android phone, the N30 Pro is plugged to port 1 when plugged/paired.

Thanks for the link! I like the idea of having to press a button to add a controller just like on Android.

Ditto, something similar to this would be great I think.
